t provide an appliance offthis kind wherein the antenna. wire is suspended on a-plurality of insulation strips carried'bythe extremities of cross arms, the" assembly being such to permit the appliance to' be'folded or com-v "pacted when not in use when extended allowing the apparatus to berealdily lnstall'ed in an attic or in theuppetrooin of a building. A still further object of theinvention is to providefan appliance of thiskindembodying the details-of! construction and in thecombination and ar Harms or cross members.
